Round One: 2011 Jeep Grand Cherokee V-8 vs. 2010 Land Rover LR4

Going off-road is easier than ever. It used to be that you'd have to manually lock hubs and shift levers (only when stopped and the transmission in neutral), and the vehicles used for off-roading were crude, uncomfortable, and bare-bones. All that has changed. Now, you can ride in luxury on the trail and can proudly take the neighbors out to dinner that night in the same vehicle. Switching to trail mode is just as easy, thanks to electronics and the creation of Terrain Response (Land Rover) and similar systems -- turn the knob to choose the terrain you're driving over, and go -- that have come along since the old days.

There are now a few sport/utilities that use a version of this technology, including the Land Rover LR4, Grand Cherokee, and Toyota 4runner, and more are on the way. Jeep said this model offers the highest level of luxury of any Grand JEEP CHEROKEE to date, without sacrificing its off-road ability. Based on a version of the Mercedes Benz M-Class platform, it's also the only one here that comes with a choice of V-6 or V-8 engines. Can it hold its own against the rugged 4Runner and the luxurious LR4?

We decided to take to the streets and the mountain back country to find out which V-6 and V-8 SUV provides the best mix of on-road comfort, luxury, and off-road capability. Our loop started in Santa Barbara, California, with freeway and highway driving. From there, we turned onto a narrow, twisting road through a well-heeled residential area (the natural habitat of vehicles like these). The paved road ends, becomes dirt, and gets much worse after that. The trail runs through the mountains of Los Padres National Forest, elevation levels change dramatically (from 37 feet in town to 4051 near Santa Ynez Peak), and all along the way, there are stunning views of the Pacific Ocean and Lake Cachuma. Once down the hill, the dirt road gives way to pavement, and the twisty two-lane joins up with Highway 101 near the beach.

Last time we had our hands on the new Ford Explorer, it finished sixth out of six in our seven-row SUV comparison test. Yes, friends, dead last. But that car was a preproduction vehicle, and quite literally...

These days, defining a sport/utility vehicle is hard. Just about anything top-heavy that necessitates the slight lifting of a passenger's leg for entry usually qualifies, thanks in part to the introduction...
